Man it might be. I'm in southern AZ and we just finished our first week of 105 + degree temps and that is when this started but her sisters aren't doing it, bone of my outdoor plants are. I gave her partial shade for a few days after I noticed it thinking it was stress, and tried pruning a chunk of it off too, and she went ahead and sprouted new growth that looks like all the other shit lol š¤· pH is at 6.8 she gets all the water she wants more or less and is planted in a really nice dappled shade area that stays much cooler than the rest of this godforsaken desert lmao. I meant to send this as a response to an answer a guy gave me, but I'm new to this app so I might post this as an answer to my own question smh, sorry if I waste anybody's time lol.
